Green Bean Casserole with Pancetta, Porcini and Parmesan

November 10, 2020 4 Comments


Through the years of adding and subtracting various dishes to my family’s Thanksgiving table, the one dish unanimously voted to ELIMINATE, as in ‘STOP making this!’ has been Green Bean Casserole!  With the canned cream of mushroom soup, canned mushrooms, the overcooked large green beans, and the canned fried onions, the old recipe was just a bunch of YUCK to my health-oriented family. 

Adios and goodbye!

I hear you!   You’re saying:  “But it’s traditional to serve this dish for Thanksgiving, right?”  It sure is!  

And that’s how this delicious recipe for Green Bean Casserole with Parmesan, Pancetta, and Porcini Mushrooms came about! Trust me, there is nothing canned or boring in this vegetable side dish!  It’s all about FRESH and making from scratch!

This recipe requires a little bit more work and time than the canned recipes, but is Soooo Worth It!  This recipe is simply indulgent!  The green beans are crispy and crunchy and lathered with a creamy, porcini, pancetta, and parmesan sauce that is simply out of this world.  The mushroom sauce is so good, it can be served on it’s own as a soup!  Topping off the whole dish are freshly fried/baked buttermilk onion rings.  Be careful, they’re delicious and hard to resist gobbling up while you’re making the rest of the recipe.  

You can also adjust this recipe easily.  If you want more green beans, not a problem.  There’s plenty of mushroom sauce.  Or maybe you want less sauce, so you simply reduce the amount in your casserole.

To create this recipe, I looked at over 25 recipes from home cooks to famous TV celebrity chefs.  I analyzed what each of the highest-rated recipes had in common.  “Fresh” had to be the first criteria that my new recipe had to be.

So What Do Recipes for Green Bean Casseroles that Use Fresh Ingredients Have in Common? 

First Of All, Every Ingredient Is FRESH, FRESH, FRESH!

Don’t use any canned green beans, no canned soup, no canned onions, and no canned mushrooms!

Select fresh, thin French green beans (Haricots Verts) instead of thicker green beans.

Use flavorful fresh or dried mushrooms such as porcini, cremini, or portabello mushrooms

Add some smoked bacon or pancetta!

Use more interesting cheeses such as Parmesan, Fontina, or Pepper Jack, just to name a few!

And prepare the fried onion topping from scratch!

And now to show you how to prepare this amazing Fresh Green Bean Casserole with Parmesan, Pancetta, and Porcini Mushrooms!

In a tall pot filled with water, blanch the green beans for about 5 minutes.  As the green beans blanch, saute’ the chopped pancetta until fully cooked and browned.

While the pancetta is sauteing, boil 3 cups of water and then place the dehydrated mushrooms in the hot water for 20 minutes.

Once the mushrooms reconstitute, drain the liquid from the mushrooms and set the liquid aside.

When the mushrooms are cooled off, give them a good chop.

This is a great time to marinate the onion rings while the pancetta sautees and the mushrooms rehydrate, 

Place the sliced onion rings in a large mixing bowl filled with fresh buttermilk.

Once the pancetta is finished cooking, place the chopped pancetta on a paper-towel-lined plate.

Discard all of the grease.

After the green beans blanch in the hot water, immediately place them in a medium-sized bowl filled with ice water.

Prepare the fried onion topping from scratch!

Now let’s prepare the cream sauce . . . oh this is yummy!In a large skillet, place the butter, onions, and garlic and cook until soft and/or a little brown.

Pour the broth into the cooked onions and garlic.

Stir in the cream and milk

Add the chopped Italian Parsley 

Mix in the pancetta

Add the green beans

Pour the entire mixture into a baking dish

Bake at 350 degrees for 20 minutes without the onions on top.

After baking for 20 minutes, scatter the onion rings on top of the casserole and bake for another 5 minutes

(or broil it, but keep an eye on it.  You don’t want these to burn!)

green bean casserole with porcini, parmesan, and pancetta

This is not your average, typical green bean casserole. This side dish is made from scratch with all fresh ingredients! Nothing comes from a can. FRESH, FRESH, FRESH!!! The flavor of the sauce is decadent and indulgent with the strong flavors of porcini mushrooms, parmesan cheese, and pancetta. Your guests will rave over this delicious recipe!

Ingredients

Buttermilk Fried/Baked Onions

  • 3 yellow onions, thinly sliced
  • 2 cups buttermilk
  • 1 cup flour
  • 3 cups panko
  • 2 Tbsp. fresh Italian parsley, minced

GREEN BEAN CASSEROLE

  • 16 oz. fresh mushrooms, sliced (I used porcini mushrooms)
  • 8 oz. of thick-cut smoked bacon or pancetta
  • 2-1/2 lbs. French green beans, fresh, ends trimmed off
  • 3 - 4 Tbsp. butter
  • 1 cup diced yellow onion
  • ⅛ tsp. cayenne pepper
  • 1-½ cups chicken/vegetable broth
  • 1-½ cups cream or half and half
  • 1-½ cups whole milk
  • 3 Tbsp. flour
  • 1 cup Parmigiano cheese, freshly-shredded
  • 4 large cloves fresh garlic, minced
  • 2 Tbsp. fresh thyme, minced
  • ½ cup, fresh Italian parsley, minced
  • ⅛ tsp. freshly grated nutmeg
  • 1 tsp. Worcestershire sauce
  • 1 tsp. kosher salt
  • ½ tsp. freshly cracked black pepper
  • Garnish: Grated Parmesan cheese
  • Optional garnish: ½ cup Italian parsley, minced
  • Optional garnish: Diced and browned pancetta

Instructions

Prepare the onion topping:

  1. Preheat oven to 475 F degrees.
  2. Separate all of the onion strips from each other and soak them in the buttermilk for 10 minutes minimum.
  3. Coat a baking sheet pan or two with nonstick cooking spray.
  4. In a large mixing bowl, mix together the breading ingredients: Flour, panko, Italian parsley, and salt. Take one handful at a time of onions that were soaking in buttermilk. Toss the onions with the dry mixture and then place them on the baking sheet pan and spread the sliced onions evenly on the pan.
  5. Place the pan on the middle rack of the oven and bake the breaded onion rings until golden brown, almost 30 minutes, giving the onions a toss 2 - 3 times during this baking period. You can also use an Air Fryer or fry them traditionally.
  6. Remove from the oven and set the onions aside to use later.
  7. Reduce the oven temperature to 400 F degrees.

While the onions are soaking and baking, prepare the mushrooms:

  1. Place the dehydrated porcini mushrooms in a medium-sized bowl and cover them with at least 3 cups of hot, boiling water, and cover with plastic wrap at least 3 cups of hot boiling water to RE-constitute.
  2. Allow them to steep in the hot water/broth for 20 minutes and then strain the liquid through a fine-mesh strainer, reserving at least 1 cup of the mushroom liquid. Set both aside.

While the mushrooms are soaking, saute' the pancetta:

  1. Saute' the chopped pancetta until fully cooked for 8 - 10 minutes. Stir occasionally and when nicely caramelized/or browned, transfer to a paper-towel-lined plate. Drain and discard the hot grease and set the pancetta aside.

While the pancetta is sauteeing, prepare the green beans:

  1. Bring a tall pot of water with 2 Tablespoons of salt to a boil.
  2. Add the green beans and blanch in the boiling water until crisp-tender and bright green (for 3 - 5 minutes).
  3. While beans are boiling, fill a very large bowl with ice water.
  4. After the 5 minute blanch in the boiling water, quickly drain the beans in a colander and immediately plunge the beans into a large bowl of ice water to stop the cooking. Drain the beans and set aside.

Prepare the sauce:

  1. Chop up the reconstituted porcini mushrooms.
  2. Melt butter in a heavy skillet on a medium-high heat stove burner.
  3. Add the chopped onions and garlic, cook, stirring until softened and the onions are caramelized about 5 minutes.
  4. Add the chopped mushrooms, 1 teaspoon salt and pepper, and cook, stirring occasionally, until the mushrooms begin to lose some of their liquid, about 10 minutes.
  5. Add the thyme, nutmeg, cayenne pepper, and Worcestershire sauce and cook for 2 more minutes.
  6. Sprinkle the flour over the mixture; stir to combine. Cook for 1 minute.
  7. Whisk in the broth and some of the reserved mushroom liquid (add a little at a time and taste as you go) and bring to a boil.
  8. Reduce the heat to medium-low and add cream, milk, parmesan cheese, and Italian parsley. Cook until the mixture thickens, stirring occasionally, for 10 - 12 minutes.
  9. Remove from the heat and stir in all of the blanched green beans and the pancetta.
  10. Transfer everything into a 3-quart baking dish (you can refrigerate this casserole, covered, for up to 4 hours, but keep the onion topping at room temperature).
  11. Bake the casserole until bubbling, about 20 minutes. Then sprinkle with the onion topping.
  12. Bake until warmed through, about another 5 minutes.
  13. Garnish (Optional) Sprinkle minced Italian parsley and diced, sauteed pancetta all over the top of the casserole.

      Well, you certainly took the boring green casserole and moved it up a few notches. The pancetta, The pancetta, the porcini mushrooms are fabulous additions. My mother’s casserole was the traditional one where a can of mushroom soup was used for the mushrooms as well as the sauce and canned fried onions. I could make a meal out of yours and I might just do that. We’re not doing a turkey this year, so just turning a wonderful side into a holiday time meal, sounds great! I hope you are doing well. I know your busy with your new position, but thrilled to see you still posting your wonderful recipes! Take care Darlin.

      Looks luscious! Confused on the mushrooms. Ingredient list says fresh porcini and directions says dried that you must put boiling water on. Which mushroom do I use?
